"My experience at Bonnot Paris was incredible from start to finish. From the very first appointment, I knew I was in good hands.
François took the time to understand my needs and preferences, and presented me with a selection of stones that were each more beautiful than the last.The design process was a true collaboration. The designer drew up 5 options and was very receptive to my comments. The end result is a bespoke ring that I adore."
Christelle
"We called on Monsieur Deprez to create our wedding rings for our wedding. From the very first appointment, he understood my husband's style. The designs are very well done, and the whole team is very attentive to any changes that need to be made. Mr. Deprez was also able to adapt perfectly to the budget he was given.
The rings are of impeccable quality. We'll be calling on him again for other projects without hesitation!"
Océane
"I am absolutely thrilled with the experience I had with Bonnot Joaillerie in creating a custom engagement ring for my fiancée.
The process was smooth and enjoyable, and the staff incredibly professional, attentive and patient. François really knew how to guide me in my choice of stones (size, quality, etc.), and their expertise and attention to detail exceeded my expectations.
The ring is simply magnificent, perfectly reflecting my fiancée's tastes and personality!"

Sapphire features
In Latin, sapphire is called "sapphirus". This term derives from the ancient Greek "sappheiros", which referred to a blue stone.
Origin of Sapphire
Geographical sources and historical background
Sapphire has been known for a long time, although it was often confused with lapis lazuli in the past. It was in 1798 that sapphire was formally identified as a corundum by two French and English mineralogists.
There are three types of rock: sedimentary, magmatic and metamorphic. Sapphire is extracted from the last two, on several continents. Some mines are rich in sapphires of particular colors, specific shades of blue or excellent quality.
Sapphire from Ceylon(Sri Lanka) is renowned for its quality, enabling the creation of jewelry. Others, such as those from Burma, Kashmir in India and Madagascar, are sought-after for jewelry. Mines are also found in Thailand, Cambodia, Australia, Brazil and the United States.
Some sapphire deposits, such as those in the Puy-de-Dôme region, are not exploited because the quality is not up to scratch.
Today, sapphire engagement rings are among the most popular jewelry items.
The value and quality of a Sapphire
How do you know the value of a sapphire?
Its value is determined by several criteria, including color, clarity, size and cut. The classic blue hue remains the most popular, although sapphires come in a wide range of colors, from yellow to pink, green and white.
It is crucial to note that the price of sapphire increases exponentially with its weight, as the larger the stone, the rarer it is.
Heat treatment also has a major influence on the price of sapphires.
Buying a sapphire is not a trivial act, since there are some excellent imitations, stones that have undergone treatments that are not reported, and others sold without a gemmological certificate, among the main risks.
maison Bonnot only sells sapphires with a certificate of authenticity issued by a gemmological laboratory, and the same goes for our other stones. We obtain them without any intermediaries, enabling us to offer you the best prices and quality guarantees. You also have a wide choice of ways to personalize a unique creation.
Sapphire processing and enhancement
What are these treatments?
High-temperature heating High-temperature heating has been used since ancient times, in traditional furnaces reaching temperatures of up to 1,800°C.
Low-temperature heating Low-temperature heating: This treatment is generally carried out between 800 and 1,200°C, and enhances the color and transparency of the sapphire while preserving its structure. It is often used for stones of less intense color, offering a subtle enhancement.
Beryllium heating This method involves heating sapphires in the presence of beryllium, a chemical element that modifies their color, in particular to intensify yellow or orange hues. Although effective, this technique is controversial, as it alters the chemical composition of the sapphire.
For this reason, Bonnot Paris chooses not to select stones that have undergone this beryllium treatment.

Our Sourcing of Precious Stones
At Bonnot Paris, we are committed to providing the finest gemstones through rigorous and ethical sourcing.
We have developed three main sourcing methods to guarantee the quality and traceability of our gems: directly from the mines, via brokers and from renowned cutting centers. Find out more about our methods below.
Directly to the mine
We favor direct partnerships with the mines, enabling us to obtain raw gemstones directly from the source.
Our partnerships span the globe, notably in Africa (Namibia, Mozambique, Tanzania, Kenya), Vietnam and Sri Lanka. By carefully selecting gems according to their quality, we then have them cut by our workshops in France and Bangkok, ensuring total control over the transformation process.
Through local brokers
Our partnerships with international brokers enable us to acquire gemstones over a wide geographical area.
These brokers, based in Africa, Brazil, Colombia and Vietnam, scour vast territories to source gems that meet our strict criteria of quality, traceability and price. The rough stones are then cut in our specialized workshops in France and Bangkok.
From the main size centers
We have offices strategically located in Jaipur, Bangkok and Beruwala (Sri Lanka).
These centers enable us to purchase pre-cut gemstones, such as Zambian emeralds in Jaipur, or sapphires and other assorted gems in Sri Lanka and Bangkok. Thanks to these offices, we can respond precisely to our customers' specific requirements, offering a wide range of top-quality stones.
More competitive prices
These three levels of sourcing enable us to offer you the best gemstones at the best prices, while guaranteeing their origin and exceptional quality.
We are committed to maintaining these standards to continue satisfying our most demanding customers.
Through Reseller Merchants
The vast majority of traditional jewelers buy their stones from dealers in their own countries.
The result is a limited choice of products and, above all, prices that are far removed from market prices.
At the jeweller's
Once again, the majority of jewellers tend to favour selling their own stones to the detriment of customers' desires.
By offering only a limited selection, the jeweler inevitably leads to a choice. At Bonnot Paris, it's the customer who chooses, and we source the ideal stone for his or her needs.
Certification and Ethics: Our Commitments
Certification and ethics are essential pillars of Maison Bonnot Paris. Every stone we offer is certified by renowned independent laboratories such as GIA, AIGS, ICA, LFG and SSEF.
This guarantees the authenticity and quality of our gems. What's more, we're proud to know the origin of the majority of the stones we offer.
Many of them come from brokers located in extraction areas we know well, ensuring impeccable traceability and ethics.
Although ethics are at the heart of our commitment, we recognize that there is still much to be done in this area.
We are determined to continue our efforts to guarantee the responsible and ethical provenance of every stone.
Certification by partner laboratories
At Bonnot Paris, every gemstone passes through our certification laboratory.
Thanks to rigorous analysis and state-of-the-art equipment, we guarantee the authenticity, purity and quality of our gems. Each stone is accompanied by a certificate of authenticity issued by our experts, ensuring our customers total transparency and absolute confidence in their investment.
